Blessed are the merciful...
Mercy is a huge subject. Some say love is all we need, walking right past this rich, beautiful word.
We could compare them like this: love is the heart, mercy is the hand. Love is the intent, mercy is the action.
As always, God takes the lead. He reaches down to us, giving us what we don't deserve. Then He says, "If you really want to be happy, follow me. Show mercy to someone else and I'll give you more."
